perf annotate: Introduce annotated_source__get_line()

It's a helper function to get annotation_line at the given offset
without using the offsets array.  The goal is to get rid of the
offsets array altogether.  It just does the linear search but I
think it's better to save memory as it won't be called in a hot
path.
